Bill Bergson, the friendly Swedish boy of Bill Bergson, Master Detective (1952) is on his merrily haphazard way again- with his pals Anders and Eva Lotta. In their small home town (where they caught a jewel thief in the last story), the kids who call themselves the White Roses have a friendly rivalry with another bunch, the Reds, and their town and country skirmishes lead to a mystery. For while hiding near Green, the money lender's house, Eva Lotta finds an I.O.U. It later helps to convict a culprit, anxiety-ridden Claus, of shady dealings to repair his debt with Green. Light mystery-light reading in a jolly Scandanavian setting.
